01:01 This is the solution

Step-by-Step Solution

To solve this problem, we'll use the properties of square roots:

  • Step 1: Apply the multiplication property of square roots in the numerator:
    2612=2612\sqrt{2} \cdot \sqrt{6} \cdot \sqrt{12} = \sqrt{2 \cdot 6 \cdot 12}
  • Step 2: Calculate the product under the square root:
    2612=1442 \cdot 6 \cdot 12 = 144
  • Step 3: Combine the expression:
    14416\frac{\sqrt{144}}{\sqrt{16}}
  • Step 4: Simplify the square roots:
    144=12\sqrt{144} = 12 and 16=4\sqrt{16} = 4
  • Step 5: Use the properties of the quotient of square roots:
    124=3\frac{12}{4} = 3

Thus, the final simplified expression is 3 \mathbf{3} .
